Building on the Napo framework, Clavitudo is a container app that will allow you to play various supported instrumental sample sets by MIDI keyboards connected to your iOS or macOS device.

The instruments have to be installed by the user. For more information, please consult the app support page https://polaron.de/Clavitudo/ , the Napo documentation at https://polaron.de/Napo/ and in particular the Napo user manual at https://polaron.de/Napo/manual/ .

The first release of Clavitudo starts with support for one instrument, namely the Aragonese Procession Organ of the Museu de la Música de Barcelona as offered for free at https://www.atmos.cat/perl?num=1444774635 .
